Abstract

Systems and methods for producing more accurate, intricate structures via digital light processing additive manufacturing are provided. One or more digital transformations, or filters, are applied to 2D-images or 3D matrices comprised of 2D images used to print the part to help eliminate the effects of light and matter interaction, as well as limitations imposed by the printing resolution of an additive manufacturing printer. The digital transformations can also be used in a diagnostic manner to help provide feedback on performance.
